This short sleeve base layer uses a premium merino blend from Italy’s Biella region, chosen for it's superior performance qualities. Exceptionally soft against the skin, it’s built to last with added synthetic fibres that improve stretch and durability. It naturally regulates your temperature, keeping you warm against wind chill and cool as your effort intensifies. The fabric is fast-wicking and odour-resistant, making it perfect for multi-day rides or back-to-back sessions.

The open mesh fabric enhances airflow, while low profile, flatlocked seams reduce chaffing and provide a smooth fit. Designed to sit close to the body, it layers seamlessly beneath your jersey.

Also available in sleeveless and long sleeve styles for versatile layering options.

Hazel E. ★★★★★ Sep 10, 2026

The merino blend is noticeably softer than the synthetic base layers I've worn for years, no itch at all against my skin. I've washed it a handful of times now and it hasn't pilled or stretched out. Just a really well-made layer.

Jacob C. ★★★★★ Sep 9, 2026

Wore this for a chilly morning hike and didn't want to take it off afterward—the Biella merino is genuinely next-level soft, not itchy in the slightest. I’ve already washed it three times and the fabric hasn’t pilled or lost its shape, which says a lot for a base layer this thin.

Riley ★★★★★ Sep 8, 2026

The fabric is hands down the softest base layer I've owned, and the short sleeves make it perfect for layering under a flannel on cool days. Wore it on a long hike and forgot I had it on, which is exactly what you want. It held its shape after a wash, too.
